臺北市永續發展指數之建構及應用

Construction and Application of Taipei’s Sustainable Development Index

永續發展指標是衡量都市是否邁向永續發展的重要工具之一，本研究依據台北市發展特性，檢討台北市歷年的永續發展指標，並參酌國內外文獻，研訂出台北市之永續發展指標，經台北市政府相關局處座談及專家學者討論後，確立51 項指標作為衡量台北市永續發展之基礎，並將51 項指標歸納到「三生一體」（生態、生活、生產、體制）架構。本研究以1995 年到2004 年資料，檢視51 項指標究竟是邁向或遠離永續，並計算四個面向的永續發展指數，最後將這四個指數合併成台北市永續發展指數，分別探討台北市四個面向及整體發展的永續變化趨勢。研究顯示，生活面向的永續發展指數大致呈現逐年遞增，顯示台北市有趨向永續發展的現象；而在生產、生態及體制面向之表現平穩，但在生產面向之永續發展指數在2002 年後有提升之趨勢，顯示台北市近年來在生產面向亦是朝向永續發展邁進。至於台北市整體發展之永續性趨勢，10 年來永續發展指數大致呈逐年上升之趨勢，顯示台北市逐步邁向永續發展。

Sustainable development indicators are one of the important tools to assess whether a city moves toward Sustainable Development (SD) or not. After taking into account the uniqueness of Taipei City, discussions with professionals, researchers and public sectors, and relevant studies, this study reviews the 48 indicators of Strategic Plan for SD of Taipei City in 2004, and then chooses 51 SD indicators fitting in the SD characteristic of Taipei City. These indicators should be regarded as a basis to assess SD of Taipei City. The 51 indicators are categorized into economic, social, environmental, and institutional dimensions. In addition, this study adopts statistical data to calculate the SD trend from 1995 to 2004. Furthermore, SD index are evaluated for the four dimensions and for Taipei City all together. Results show that indicators in the social dimensions move toward SD, while economic, environmental and institutional dimensions perform comparatively meager. However, since 2002, the economic SD index has steadily progressed toward SD. As to Taipei Sustainable Development Index, the trend demonstrates that, during the past 10 years, Taipei has gradually moved toward sustainable development.
